我们了解什么记录和什么不记录汉堡王申请


本文是对fennikami关于不良汉堡王如何从智能手机屏幕录制视频的文章的回应。 原始文章声称，汉堡王可以通过这种方式访问​​有关输入卡的信息，从而破坏了输入卡。 我将尝试弄清楚是否确实如此。
借助评论中张贴的一条小指令，您可以独立接收Appsee发送的视频。 并确保修饰哪些数据，哪些不修饰。

我分析了一个Android应用版本2.2.2，更新日期为2018年7月9日。 其他平台和应用程序不同版本上的结果可能与本文给出的结果不同。

初始化Appsee


Appsee是用于改善客户端应用程序的用户体验的分析系统之一。 当您在应用程序中时，它将记录屏幕和您的操作。 总体而言，这没什么不对； Yandex的WebVizor技术在Web上得到了广泛传播，其目的是相同的。

在其工作的初始阶段，Appsee向服务器请求针对特定应用程序的配置，正是该请求被作者捕获在原始文章中，在我的情况下，答案看起来像这样：

{ "AutoDetectScreens": true, "AutoHideWebComponents": true, "ClientId": "5b47182e7b2f3f1429341f73", "ClientLogsUploadPolicy": 2, "ConfigHttpTimeoutInMilliseconds": 5000, "DetectActions": true, "DetectCrashes": true, "DetectGestures": true, "DetectMenus": true, "DetectPopups": true, "HideInput": true, "HideSensitiveViews": true, "MaxEventProperties": 5001, "MaxVideoLength": 0, "OfflineConfigurationPolicy": 1, "RecordMetadata": true, "RecordVideo": true, "SensitiveMaskingPerWindow": true, "SessionId": "5b4718ec470302299bdcc04d", "TrackedOfflineSessions": {}, "UploadAppIcon": false, "UploadBenchmarks": false, "UploadTouchEvents": true, "UploadVideoOnCrash": true, "UseWebViewSnapshotFullscreen": false, "VideoBitrate": 56, "VideoFPS": 3, "VideoHeight": 320, "VideoWidth": 160 }

您会注意到HideInput ， HideSensitiveViews参数为true，从而在视频中隐藏了重要信息。 有关如何确定信息的重要性的问题立即出现，对于答案，我们转向Appsee文档 。 简而言之，默认情况下，所有用于输入数据的字段都是隐藏的；此外，您可以配置其他字段或界面部分的隐藏。

我们还注意视频记录的质量，在我的情况下，它是分辨率为320 x 160像素，每秒三帧的视频。

Appsee收集的真实数据


我决定检查真正发送到Appsee服务器的数据，为此，我使用了Burp Suite中的Proxy。 首先，分析系统使用应用程序内部的用户操作来传输文件，包括用户在此单击的坐标，不记录击键。

Appsee收集的数据，用户操作

视频传输到Appsee服务器，正如预期的那样，大多数数据被隐藏


我们看看接下来会发生什么


appsee似乎很安全，很可能帮助开发人员多次改进了该应用程序。 但是，接下来让我们检查一下地图数据会发生什么。 首先，您需要阅读媒体上汉堡王代表的评论：
“带有远程订单的Burger King移动应用程序不会收集其订户的个人数据。 所有交易均受到该国最好的收购方之一-Yandex.Kassa的可靠保护。 该公司表示，有关应用程序中用户行为的数据不包含有关银行卡的信息，也不存储在服务器上。
这听起来很有说服力，现在我们来看一下实际流量。 对于付款，实际上使用的是Yandex的处理方式，具体取决于地址

https://payment.yandex.net/api/v2/payments/bankCard

请求有效负载是带有一些数据的请求参数：

那些至少使用过JSON Web令牌的人立即注意到它是他。 使用在线解码器，我们可以获得源数据。 通常，关于在线处理的信息不会传送给发给他的有关卡的信息

 { "order": { "clientOrderId": "2a6da014-28e0-4560-a057-76160c8cc3ca", "customerId": "", "value": { "amount": "1.00", "currency": "RUB" }, "parameters": { "cardUUID": "7a904e18-d945-4128-8207-187d1a081b34", "userId": 258504, "addCard": true } }, "expiryYear": "2025", "extAuthFailUri": "https://orderapp.burgerking.ru/api/v1/pay/failed", "source": "BankCard", "recipient": { "shopId": "145363", "shopArticleId": "449532" }, "csc": "222", "pan": "2225555255366666", "createRecurring": true, "extAuthSuccessUri": "https://orderapp.burgerking.ru/api/v1/pay/success", "expiryMonth": "10" }

最初，下一部分包含关于记录有关地图的所有信息的错误假设；在注释中注释了staticlab之后，有关记录的部分已更改。 我向误导的读者们表示歉意。

围绕头部的日志


似乎出了什么问题，应该在Yandex.Kassa上可靠地处理卡。 如果Burger King应用程序的开发人员没有决定为自己添加一些日志记录。 因此，尽管如此，收集有关卡的一些信息，尤其是卡的最后4位数字，卡到期的月份和年份。 包含以下信息的日志将发送到：

https://orderapp.burgerking.ru/api/v1/log/requests

成功和不成功尝试发送数据都会导致处理卡。 我几乎可以确定日志已保存，否则为什么要发送日志？

结论


  1. 分析是正常的，当然，我想提出更“生动”的警告。 没有分析，就不可能开发大型和复杂的应用程序。
  2. 但是，地图上的某些数据很可能是无意收集的。
